ABSTRACT:
Improved apparatus for forming multilayered thermoplastic articles employing a blow slot equipped, porous metal section equipped core rod. In addition to control means, the apparatus employs means for opening and closing the blow slot of the core rod, detachable connection means for connecting an internal fluid passageway in said core rod with a vacuum source, and other detachable connection means for connecting such internal fluid passageway with a pressurized fluid source. In addition, check valve means is provided for closing said internal fluid passageway when the internal fluid passageway is detached from the detachable connection means joining such with a vacuum source. The vacuum source is connectable with the core rod at the time of liner loading and the pressurized fluid source is connected with the core rod at the time of blow molding.
